8 Best Fly.io Alternatives (2026)
The closest alternatives to Fly.io are AWS Amplify Hosting, Cloudflare Workers & Pages, Coolify and Deno Deploy, with 4 more below. Each shares a comparison category with it, so every rationale here names both tools' real values. Fly.io is 10th of 13 on Free tier (2) — usually where a switch starts.
Why do people look for Fly.io alternatives?
Most people searching for Fly.io alternatives are not shopping — they already run it and something has stopped fitting. That something is usually a specific number rather than a feeling, so this page starts from the fields where Fly.io genuinely trails the rosters it appears in, and only then covers the reasons that never show up in a table.
The measured reasons.
- Free tier — 2, 10th of 13. Cloudflare Workers & Pages records 5.
Any one of those is enough on its own if you sized your architecture around it. None of them is enough if you didn't — which is why the list is short and specific rather than a general case against Fly.io.
The reasons that never make it into a table. A price rise after a funding round. A licence change that turns a self-host into a subscription. A region you now need and they do not have. An acquisition. A support experience that quietly degrades. None of those are fields, and all of them move teams — which is why every entry below links back to Vercel alternatives, where the full field set and its sources live. The ones we catch get logged on the Fly.io timeline.
How the shortlist is ordered. Every tool below shares at least one comparison category with Fly.io, sorted by how many categories the two overlap in. There is no editorial ranking, no sponsorship and no affiliate link — the order is the overlap count, and the rationale under each is generated from the two tools' own cells, so it names real values rather than adjectives.
1.
AWS Amplify Hosting
AWS Amplify Hosting — Managed Next.js and static hosting inside AWS, billed per GB with no spend cap. It meets Fly.io in Vercel alternatives. It is ahead on Preview deploys (Yes against Partial), Rollback (instant against redeploy) and Next.js parity (most against self-managed). What you give up: CLI quality (2, where Fly.io records 5) and Cron jobs (No, where Fly.io records Partial). Best for apps whose data already lives in AWS, especially in Sydney. Only worth it when the rest of the stack is already in AWS and the app needs to sit next to your data in ap-southeast-2. Otherwise you are paying Vercel-tier bandwidth prices for worse cold starts, no cron, and CloudWatch as your logging product.

2.
Cloudflare Workers & Pages
Cloudflare Workers & Pages — V8 isolates on 300+ PoPs, with zero egress charges and near-zero cold starts. It meets Fly.io in Vercel alternatives. It is ahead on Free tier (5 against 2), Self-hostable (Partial against No) and Runtime model (edge-only against container). What you give up: Exit friction (4, where Fly.io records 2) and Monorepo support (Partial, where Fly.io records Yes). Best for anything where a traffic spike must not produce a four-figure invoice. The correct answer if the bill is why you are reading this: free egress turns the entire overage question into a footnote. You pay for it with a non-Node runtime and a Next.js path maintained by the community rather than the framework team.

3.
Coolify
Coolify — Open-source self-hosted PaaS: git push to your own server, with previews and cron. It meets Fly.io in Vercel alternatives. It is ahead on Self-hostable (Yes against No), Overage behaviour (throttle against bill) and Free tier (5 against 2). What you give up: CLI quality (2, where Fly.io records 5) and WAF & DDoS (No, where Fly.io records Partial). Best for teams that already run servers and resent the Vercel invoice. Astonishingly complete for free software — previews, cron, TLS and databases all work — and one of only two rows where a traffic spike degrades instead of billing. What you take on is the pager, the disk-space alerts and the fact that nobody is coming to help at 3am.

4.
Deno Deploy
Deno Deploy — Web-standard JavaScript at the edge, with built-in OpenTelemetry and a global KV. It meets Fly.io in Vercel alternatives. It is ahead on Runtime model (edge-only against container), Free tier (4 against 2) and Preview deploys (Yes against Partial). What you give up: Image opt billing (none, where Fly.io records byo) and Monorepo support (Partial, where Fly.io records Yes). Best for web-standard TypeScript services and APIs. The best out-of-the-box observability story on this page and a genuinely pleasant runtime if you write web-standard JavaScript. It is also the smallest platform here, with a pricing model that has been rebuilt more than once: fine for services, risky as the foundation of a business.

Dokploy
Dokploy — Open-source self-hosted PaaS on Docker Swarm, with multi-node clustering built in. It meets Fly.io in Vercel alternatives. It is ahead on Self-hostable (Yes against No), Overage behaviour (throttle against bill) and Free tier (5 against 2). What you give up: CLI quality (2, where Fly.io records 5) and WAF & DDoS (No, where Fly.io records Partial). Best for self-hosters who need more than one node from day one. Coolify's architecture argument in reverse: Docker Swarm underneath means multi-node clustering and rolling deploys across several boxes with no extra tooling. Younger, smaller ecosystem, fewer templates — pick it over Coolify specifically when you expect to outgrow one server.

6.Hetzner + Coolify
Hetzner + Coolify — The DIY baseline: a €4 CX22 running Coolify, with 20 TB of traffic included. It meets Fly.io in Vercel alternatives. It is ahead on Self-hostable (Yes against No), Pricing clarity (5 against 3) and Preview deploys (Yes against Partial). What you give up: Sydney region (No, where Fly.io records Yes) and CLI quality (2, where Fly.io records 5). Best for benchmarking whether a managed host is worth its markup. The number every managed host is implicitly arguing against: about $5 a month with 20 TB of traffic included and an overage rate of €1/TB. Nothing scales automatically, there is no Australian region and the pager is yours — but you should know what the floor costs before agreeing to sit above it. Note that we carry Hetzner + Coolify as the do-it-yourself baseline in that roster — the "what if we just ran this ourselves" reference point. The honest answer is usually that it is cheaper and considerably more work.

Netlify
Netlify — The original Jamstack host: strong build pipeline, punishing bandwidth overage. It meets Fly.io in Vercel alternatives. It is ahead on Runtime model (edge+node against container), Preview deploys (Yes against Partial) and Cron jobs (Yes against Partial). What you give up: Bandwidth price ($550 /TB, where Fly.io records $20 /TB) and Sydney region (Partial, where Fly.io records Yes). Best for content sites with steady, forecastable traffic. A very good build pipeline attached to the worst egress pricing in the category. If your traffic is predictable and modest it is a fine Vercel substitute; if it is spiky, the $55-per-100 GB overage is a documented hazard rather than a theoretical one.

Northflank
Northflank — Container platform with bring-your-own-cloud, GPUs and a sandbox-shaped API. It meets Fly.io in Vercel alternatives. It is ahead on Self-hostable (Partial against No), Preview deploys (Yes against Partial) and Cron jobs (Yes against Partial). What you give up: Sydney region (Partial, where Fly.io records Yes) and CLI quality (4, where Fly.io records 5). Best for teams that need workloads inside their own cloud account for compliance. The most capable platform on this page that nobody shortlists. Preview environments and jobs beat Railway's, and bring-your-own-cloud is the only route to Sydney compute under a managed control plane. Its published pricing is the least legible thing about it.

How this list was built
There is no editorial ranking on this page and no sponsorship behind it. The order is mechanical: every tool that shares a comparison category with Fly.io, sorted by how many categories the two overlap in. A tool that meets Fly.io in three rosters sits above one that meets it in a single roster, because more overlap means the comparison is more like-for-like.
The rationale under each entry is composed from the two tools' own cells. Where they differ on a field we score, the sentence names both values and the unit. Where they don't differ, it says so instead of manufacturing a distinction — which is why some entries are short.
Values, sources and verification dates all live on the category tables: Vercel alternatives. If a figure here disagrees with a vendor's current pricing page, the vendor is right and we are stale.
Still deciding whether to move at all? The Fly.io profile has the when-to-use and when-not-to-use blocks, and the Fly.io timeline has the dated changes that usually trigger a migration.
